I am using WAS 5.0 as server. My application executed correctly in case of Websphere studio 5.0. But i used the same configuration in Websphere server 5.0. I had created Queue connection factory and Queue destination in Websphere JMS Provider and also i had created Listener port in server configuration. I did'nt used MQ provider. But i got the Exception javax.jms.InvalidDetinationException:Failed to open MQ Queue. Can any one help me sort out this problem
